vim-patch:8.2.3575: overflow check still fails when sizeof(int) == sizeof(long)
Problem: Overflow check still fails when sizeof(int) == sizeof(long).
Solution: Use a float to check the result.
https://github.com/vim/vim/commit/e551ccfb9311eea5252d1c3106ff7a53c762d994
This approach is... interesting...
Tests fail.
